Container for lubricating oil



y 1936- w. v. MYERS ammezs CONTAINER FOR LUBRICATING OIL Filed July 2,1955 INVE TOR ATTO RN EYS Patented May 12, 1936 UNITED STATES PATENTOFFICE Application July 2, 1935, Serial No. 29,464 In Great Britain July12, 1934 3 Claims.

The invention relates to tins or containers in which oil is put up andsold and to tins or containers of this kind which are provided with afilling and outlet nozzle that is closed by a cap or a hollow plug.

The main object of the invention is to provide tins or containers of thekind above referred to with means by which they can be used aslubricating cans, said means being of such nature that the spout forminga part of said means can for practically the whole of its length behoused within the body of the tin or container when the latter is notrequired to be used for lubricating.

The improvements constituting the present invention may however be usedin the case of 1ubrieating or oiling cans and in the case of large drumsor other large receptacles containing oil.

According to the invention a screwed cap or closure member is used forclosing the filling and outlet nozzle of a tin or container in which oilis put up and sold and is provided with an externally screw-threadednipple, which serves as a guide for a tube or delivery spout which issecured in any position in the nipple and a liquidtight joint obtainedbetween the tube or delivery spout and the nipple by means of a cap nutengaging with the nipple and packing interposed between the outer end ofthe nipple and the cap nut.

In the applications of the invention to drums or like large receptaclesfor oil and to lubricating or oiling cans the same combination ofextensible tube or delivery spout, externally screwthreaded nipple, capnut and packing would be employed, but in this case the closure membermay for example comprise a nipple having external threads to screw intothe container and a cap having internal threads to screw over thenipple.

The accompanying drawing illustrates, by way of example, the applicationof the invention to a tin or container of the kind in which oil is putup and sold and the filling and outlet nozzle of the tin or container isclosed by a screwed cap.

Fig. l of the accompanying drawing is an elevation of a tin or containerof the kind last referred to provided with the invention, the spout ordelivery tube being shown in its innermost position in the body of thetin or container. Fig. 2 is a vertical section of the same tin orcontainer with the spout or delivery tube, shown mainly in elevation,fully extended.

Referring now to the drawing, I is the screwed cap which engages withand closes the filling and outlet nozzle 2 of the tin or container. 3 isa nipple which is secured to the cap I and is pro- 5 vided on itsexterior with screw threads, and serves as a guide and support for aslidable tube 4, that constitutes the delivery spout of the tin orcontainer when the latter is to be used for lubricating or oiling. Theslidable tube 4, which is either expanded at its inner end, as shown inthe drawing, or is provided at its inner end with a nut, so that itcannot be wholly withdrawn from the tin or container, and is fitted witha closing cap 5 at its outer end, is made of uniform diameter on itsexterior and of a diameter which is slightly less than the bore of thenipple 3. The tube 4, usually (though not necessarily) will be straightthroughout its length and is secured in any desired position in thenipple 3, with more or less of the tube 4 projecting beyond the body ofthe tin or container and with the outer end of the tube if bent pointingin any desired direction, and a liquid-tight joint obtained between thetube 4 and the nipple 3 by means of a cap nut 6, which is engaged withthe screw threads provided on the exterior of the nipple 3, and apacking l of leather, oil-proof rubber, or other suitable material thatis interposed between the outer end of the nipple 3 and the inner faceof the cap nut 6. The cap nut 6 is preferably coned on its inner face,as shown in Fig. 2, to ensure the central part of the packing I beingpressed against the exterior of the slidable tube 4 when the cap nut 6is screwed onto the nipple 3 to form a liquid-tight joint between thelatter and the tube.

In the case of the application of the invention to tins or containers inwhich the filling and outlet nozzle of a tin or container is closed bymeans of a screwed hollow plug the same arrangement and construction ofparts as illustrated by the drawing would be used, it being understoodthat the externally screwed nipple would be made of such length as toallow of the cap nut which engages with the nipple being readilymanipulated.

The invention possesses many advantages among which are the following:

The spout of the present invention by reason of the fact that it can behoused for the greater part of its length in the body of a tin or thelike ensures the latter occupying a minimum amount of space andconsequential compact packing and. ready transportation of tins or thelike provided with the invention. Further, by reason of the fact thatthe inner end of said spout can always be located below the uppersurface of the oil in a tin or the like delivery of oil from the spoutmay be effected whilst a tin or the like is in an upright position bymerely pressing on the sides of the latter.

As above-mentioned the invention can, if desired, be used with drums orlike large receptacles for oil. In this case the solid plug closing thefilling and outlet orifice of a drum or the like is replaced by anexternally screwed tubular extension and on this extension is screwed acap to which is secured the hereinbefore mentioned screwed nipple thatacts as a guide for the slidable tube or spout, indicated by 4 in theaccompanying drawing.

Further, as stated above, the invention can be applied to lubricating oroiling cans, all that is necessary in this case being to provide thebody of a can with an externally screw-threaded tubular extension. Thistubular extension, as in the case of the tubular extension of a drum orlike receptacle, is provided with a screwed cap to which cap is securedan externally screwed nipple similar to and serving the same purpose asthe screwed nipple used in the previously described embodiments of theinvention.

I claim:

1. In combination, a container for oil or the like having. a threadedoutlet, a closure member for such outlet having threads adapted toengage with the threads of the outlet, a hollow nipple forming part ofsuch closure member having an externally threaded portion extendingoutwardly, a discharge tube slidably mounted in said nipple, a cap nutengaging the external threads of said nipple and also surrounding saiddischarge tube, and a packing between the outer end of the nipple andthe cap nut such that by tightening the cap nut the discharge tube maybe held substantially leak-proof in any desired position.

2. A structure as specified in claim 1, in which the closure membercomprises a nipple having external threads and a cap having internalthreads to screw over one end of such nipple.

3. A structure as specified in claim 1, in which the container comprisesa body portion having an externally threaded tubular extension and inwhich the closure member comprises a cap adapted to screw over suchextension.
